4.2.PRELIMINARIES

Check that the indication for type of appliance (category and type of gas calibration) reported on the label of characteristics corresponds to the gas family / group of the gas supply.

A

The type of of appliance does not

 

The appliance cannot be installed or put into operation.

correspond to the gas family of the

 

 

 

 

 

 

gas supply

 

 

 

 

 

 

B

The type of appliance corresponds

Domestic hot water:

Check the regulation according to section 4.3

to the gas family of the gas supply

Heating:

In the event of the heating power setting being different from the

 

 

 

 

thermal power setting required, the gas must be adjusted as in

 

 

 

section 4.3. Otherwise, it is enough to check the

 

 

 

correspondence.

 

 

 

 

C

The type of appliance does not

Domestic hot water:

Transform the boiler in accordance with section 4.5, after which:

correspond to the gas supply group

Heating:

Check the regulation in accordance with 4.3

 

 

(but corresponds to the family).

 

Carry out the gas regulation in accordance with point 4.3 in

 

 

 

keeping with the thermal power requested.

 

 

 

 

4.3.GAS REGULATION

To regulate the gas, the sequence described below must be followed.

-Unscrew by 2 to 3 rotations the sealing screws marked “PE” of the pressure measurement inlet nipple

-Connect up a pressure gauge

-Place the appliance in operation in accordance with the usage manual

-Measure the connection pressure (dynamic pressure)

4.3.1.INLET PRESSURE TEST

This pressure, for methane gas, must be between 18 and 25 mbar. In the event that the pressure is outside of the above range, the boiler must not be placed in operation.

-Turn off the boiler.

-Remove the pressure gauge.

-Screw in the sealing screws of the pressure measurement inlet nipple and check the seal.

If it proves impossible to eliminate the defect, contact the gas supply board.

4.3.2.REGULATION OF THE THERMAL POWER

For the regulation of the gas in the ecoGENUS, two separate operations are required.

A)Domestic hot water side (test only)

B)Heating side (regulation and test)

A)DOMESTIC HOT WATER:

The thermal power for the hot water is set in the factory at the maximum power.

For this reason the boiler does not need any regulation of the gas from the "domestic hot water" side, just a test using the volumetric method at the gas meter:

-Make sure that there are no other gas appliances in operation during the test.

-Place the boiler in operation in accordance with the usage manual and draw hot water (tap totally open, temperature knob at 9).

NOTE: the test of the volumetric rate of flow must be carried out for at least two minutes of boiler operating time.

-Identify the volumetric rate of flow for the maximum thermal power from the table at the end of this section.
